I has a couple of prop bolts shear off inside the prop hub. I have removed the main prop stud. I wanted to remove the prop hub so that I could apply heat to it to remove the sheared off bolts using a left-hand drill bit. Anyone having any experience in removing a ZDZ prop hub? I have put a gear puller on it with a socket head cap screw installed where the prop stud goes, but it does not want to move.
Sharing actual experience would be appreciated!

My buddy used a press and a tool that slipped behind the hub. We put a socket on the crank, and the tool rested on the press with the engine hanging below it. As he cranked the press, it pushed on the socket, which in turned pushed the engine downward. I had to hold the engine to make sure it wouldn't hit the floor.

Here is a picture of the tool. We didn't use the part that you screw down. We just used the socket and press.

I bought a gear puller from Sears. The fingers were small enough to get in behind the hub. I installed a socket head cap screw in the center, so I was pushing off of the SHCS and not the end of the crank. I applied preload pressure, then added heat to the hub using a propane torch. After applying some heat to the hub, is started to move - FINALLY! I got it off.
Now to repair the hub.
Thanks for the replies!
